This research brief uses data from the American Indian and Alaska Native Head Start Family and Child Experiences Survey (AI/AN FACES) 2015 (see Box 2) to provide nationally representative descriptive information about children's Native language and culture experiences in their Region XI classrooms and programs. AI/AN FACES 2015 was the first national study of Region XI Head Start. The members of the AI/ AN FACES Workgroup, which includes Region XI Head Start directors, researchers, and federal program staff, provided input on the study's design, implementation, and dissemination (Malone et al., 2018). Among the Workgroup members' priorities was that the study provide a portrait of Region XI children's Native language and culture experiences. In this brief, data from teachers, center directors, and program directors in the spring of 2016 (see Box 2) are used to describe children's experiences in their Head Start classrooms and programs.
